External Affairs refers to the activities and policies that a government or organization engages in to manage its relationships with other countries or entities. This includes diplomacy, trade negotiations, and international cooperation on issues like security and environmental concerns. The goal is to promote national interests and foster positive relations with other nations. In many countries, the department responsible for External Affairs is often called the Ministry of Foreign Affairs or Department of State. These agencies handle communication with foreign governments, represent national interests abroad, and work on treaties and agreements that affect international relations.
